IMPROVEMENT IN SNAPS FOR BRACELETS, 8m.

Tho Schedule referred to in these Letters Patent and making part of the same To all whom it may concern:

Be it known that I, GEORGE S. GRANT, of the city and county' of Providence, in the State of Rhode Island, have inventeda new and useful Improvement on do hereby declare that the following is a full and exact description thereof, reference being had to the aeemnpanying drawings, and to the letters and figures of reference marked thereon.

Heretofore there has been great inconvenience and loss occasioned by the facility with which the ordinary snaps or clicks on bracelets, necklaces, Ste., become unclasped; and

Thenature of my` invention consists in providing an ordinary snap, with a locking-device, to prevent its ordinary u nclasping, except by manipulation.

'.lo enable others skilled in the art to make and use my invention, I will proceed to describe its construev tion and operation.

Figure l is a sectional transverse view of the snap and its frame with the spring locked.

Figure 2 is a sectional transverse view of the snap and its frame with the springr unlocked.

Figure 3 is a Vertical sectional view of the snap, its fra-lne, and its post.

In the post a, fig. 2, which is set loose in an ordinary snap-frame', a mortise or slot, al, g. 2, is cut sufleiently longr and deep to permit the ends of the spring b, iig. 2, to approach each other, the post ya being held in its position by the spring b, as in ordinary snaps.

Now, at the ends of the mortise or slot el, iig. 1, two other slots or mortises, c c2, fig. 1, are eut at angles greater or less than right angles, as the-case may be, so that when the post a is made to revolve in its bearings the end of the spring b and the edge of the plate or plane g enter the mortises or slots c" c2, as seen in fig. 1, and the post a cannot be depressed because held by the plane or plate g, in thel mortise or slot cz,- and the lip of the spring b is held at and in the mortise or slot c, iig. 1, lest anyv jar might cause that to be depressed and the snap to be unclasped.

In iig. 1, the slot e, in the head of the post a, is merely an indicator to show whether the snap is locked or unlocked. y

It is evident that this improvement can be applied not only to bracelet and necklace, butto many other articles, where the snaps are used, or can be used, with advantage.

What I ela-im as my invention, is-

The application of'mortises or slots, or their equivalents, to the post of the snap, for the purpose of locking the snap, substantially as herein described.

GEORGE S. GRANT.
